WorldViz User Forum - How to use precipitation.dle?

After adding the plug-in you can either create a snow or rain object from that. Each one has methods that allow you to set the size, speed, and wind for the particles. Here is a sample script that you can use to change the effects.

Code:

import viz

viz.go()



viz.add('tut_ground.wrl')



precip = viz.add('precipitation.dle')

snow = precip.snow(1)



import vizmenu

menu = vizmenu.add()

OptionsMenu = menu.add('Options')

SpeedSlider = OptionsMenu.add(viz.PROGRESS_BAR,'Default','Speed')

SizeSlider = OptionsMenu.add(viz.PROGRESS_BAR,'Default','Size')

WindSlider = OptionsMenu.add(viz.PROGRESS_BAR,'0.00','Wind')

WindSlider.set(0.5)



def onSpeed(pos):

        val = pos*10

        snow.setSpeed(val)

        SpeedSlider.message('%.2f'%(val))

vizact.onslider(SpeedSlider,onSpeed)



def onSize(pos):

        val = pos*0.1

        snow.setSize(val)

        SizeSlider.message('%.2f'%(val))

vizact.onslider(SizeSlider,onSize)



def onWind(pos):

        val = pos*20 - 10

        snow.setWind([val,0,0])

        WindSlider.message('%.2f'%(val))

vizact.onslider(WindSlider,onWind)
